Think mobile devices are low-power? A study by the Center for Energy-Efficient Telecommunications—a joint effort between AT&T’s Bell Labs and the University of Melbourne in Australia—finds that wireless networking infrastructure worldwide accounts for 10 times more power consumption than data centers worldwide. In total, it is responsible for 90 percent of the power usage by cloud infrastructure. And that consumption is growing fast.

Imagine you have broken your smart phone, and you can’t replace it for a few days. You go around the house looking for all the things that your smart phone replaced, so you can at least get by until you get your phone replaced.

So what does the PlayBook have to offer? It turns out, quite a lot. Featuring a 7″ screen (much like the newSamsung Galaxy Tab), the PlayBook sports a 1Ghz dual-core processor, has 1GB of RAM, and touts the ability to multi-task and run Flash 10.1.

To a large extent, the PlayBook looks like it’s a showcase of RIM’s acquisition of QNX. QNX Neutrino is the base of the new OS.

RIM is selling this as the first “enterprise-ready” professional tablet.
